Negative.
I can say with almost 90% certainty that people ALT-F4'ing out of missions are causing a runtime error in the serverplatform. Maybe not all of them, but I believe this does cause the serverkit to crash. I reproduced it twice last night. Might be prudent to conduct a small, quick test.
Tracey - Bonk, please see the Serverkit Dev thread for more details.
